Conditions + +Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted +in Section 2.1. + +3. Responsibilities +------------------- + +3.1. Distribution of Source Form + +All distribution of Covered Software in Source Code Form, including any +Modifications that You create or to which You contribute, must be under +the terms of this License. You must inform recipients that the Source +Code Form of the Covered Software is governed by the terms of this +License, and how they can obtain a copy of this License. You may not +attempt to alter or restrict the recipients' rights in the Source Code +Form. + +3.2. Distribution of Executable Form + +If You distribute Covered Software in Executable Form then: + +(a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more + than the cost of distribution to the recipient; and + +(b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter + the recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + +You may create and distribute a Larger Work under terms of Your choice, +provided that You also comply with the requirements of this License for +the Covered Software. If the Larger Work is a combination of Covered +Software with a work governed by one or more Secondary Licenses, and the +Covered Software is not Incompatible With Secondary Licenses, this +License permits You to additionally distribute such Covered Software +under the terms of such Secondary License(s), so that the recipient of +the Larger Work may, at their option, further distribute the Covered +Software under the terms of either this License or such Secondary +License(s). + +3.4. Notices + +You may not remove or alter the substance of any license notices +(including copyright notices, patent notices, disclaimers of warranty, +or limitations of liability) contained within the Source Code Form of +the Covered Software, except that You may alter any license notices to +the extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + +You may choose to offer, and to charge a fee for, warranty, support, +indemnity or liability obligations to one or more recipients of Covered +Software. However, You may do so only on Your own behalf, and not on +behalf of any Contributor. You must make it absolutely clear that any +such warranty, support, indemnity, or liability obligation is offered by +You alone, and You hereby agree to indemnify every Contributor for any +liability incurred by such Contributor as a result of warranty, support, +indemnity or liability terms You offer. You may include additional +disclaimers of warranty and limitations of liability specific to any +jurisdiction. + +4. Inability to Comply Due to Statute or Regulation +--------------------------------------------------- + +If it is impossible for You to comply with any of the terms of this +License with respect to some or all of the Covered Software due to +statute, judicial order, or regulation then You must: (a) comply with +the terms of this License to the maximum extent possible; and (b) +describe the limitations and the code they affect. Such description must +be placed in a text file included with all distributions of the Covered +Software under this License. Except to the extent prohibited by statute +or regulation, such description must be sufficiently detailed for a +recipient of ordinary skill to be able to understand it. + +5. Termination +-------------- + +5.1. The rights granted under this License will terminate automatically +if You fail to comply with any of its terms. However, if You become +compliant, then the rights granted under this License from a particular +Contributor are reinstated (a) provisionally, unless and until such +Contributor explicitly and finally terminates Your grants, and (b) on an +ongoing basis, if such Contributor fails to notify You of the +non-compliance by some reasonable means prior to 60 days after You have +come back into compliance. Moreover, Your grants from a particular +Contributor are reinstated on an ongoing basis if such Contributor +notifies You of the non-compliance by some reasonable means, this is the +first time You have received notice of non-compliance with this License +from such Contributor, and You become compliant prior to 30 days after +Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent +infringement claim (excluding declaratory judgment actions, +counter-claims, and cross-claims) alleging that a Contributor Version +directly or indirectly infringes any patent, then the rights granted to +You by any and all Contributors for the Covered Software under Section +2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all +end user license agreements (excluding distributors and resellers) which +have been validly granted by You or Your distributors under this License +prior to termination shall survive termination. + +************************************************************************ +* * +* 6.

The file is opened with the O_EXCL flag, +* guaranteeing that the caller is the only user. The filename will consist +* of the string given by `prefix` followed by 10 random characters. If +* `prefix` is NULL, then the string "tmp." will be used instead. The file +* will be created in an appropriate directory chosen by the first +* successful attempt in the following sequence: +* +* a) The directory given by the `dir` argument (so the caller can specify +* a secure directory to take precedence). +* +* b) The directory name in the environment variables: +* +* (i) "TMP" [Windows only] +* (ii) "TEMP" [Windows only] +* (iii) "TMPDIR" [Unix only] +* +* c) `P_tmpdir` as defined in [Unix only] (in Windows, this is +* usually "\", which is no good). +* +* d) The current working directory. +* +* If a file cannot be created in any of the above directories, then the +* function fails and NULL is returned. +* +* If the argument `pathname` is not a null pointer, then it will point to +* the full pathname of the file. The pathname is allocated using `malloc` +* and therefore should be freed by `free`. +* +* If `keep` is nonzero and `pathname` is not a null pointer, then the file +* will be kept after it is closed. Otherwise the file will be +* automatically deleted when it is closed or the program terminates. +* +* +* RETURN VALUE +* The tmpfileplus() function returns a pointer to the open file stream, +* or NULL if a unique file cannot be opened. +* +* +* ERRORS +* ENOMEM Not enough memory to allocate filename. +* +*/ + +/* ADDED IN v2.0 */ + +/* +* NAME +* tmpfileplus_f - create a unique temporary file with filename stored in a fixed-length buffer +* +* SYNOPSIS +* FILE *tmpfileplus_f(const char *dir, const char *prefix, char *pathnamebuf, size_t pathsize, int keep); +* +* DESCRIPTION +* Same as tmpfileplus() except receives filename in a fixed-length buffer.
