2017-08-07Adding info functions to proj.h API. (#551)Kristian Evers
* Adding info functions to proj.h API. Four new functions are added with this commit: proj_info(), proj_pj_info(), proj_grid_info() and proj_init_info(). Additionally four new data types are added: PJ_INFO, PJ_PROJ_INFO, PJ_GRID_INFO and PJ_INIT_INFO. The functions return the corresponding data types. These functions allows users of the PROJ.4 library to get information about various PROJ.4 entities and the library itself. The new data types are structs that contain specific information about either the library instance, a PJ instance, a grid or an init file. Together the four new functions cover a big part of the functionality in the semi-public projects.h API and should hopefully make it easier for user to migrate their code to the proj.h API in the future. Besides covering already existing functionality in the old API, this commit introduces the ability to add metadata to init-files. This is primarily added to give users a way of knowing which version of the EPSG database they are using, but it also comes in handy for other init-files. The init-file metadata is added directly to the init-file as a special "projection" called "metadata". The info projection of the epsg init-file is thus described as: <metadata> +version=9.0.0 +origin=EPSG +lastupdate=2017-01-10 The proj_init_info() function uses the internal pj_param() to read the metadata. As a consequence, "metadata" will not be available as a the name of a projection in the future. This is a reasonable price to pay considering the ease of the implementation of adding metadata to init-files this way, and of course that "metadata" is a very unlikely name for a projection in any case. A metadata tag has been added to all init-files in the nad-directory. For most only a subset of the possible parameters has been added. * Replaced calls to sprintf and strncpy with safer options. Added pj_strlcpy for internal use. * Fail gracefully when getting non-initialized PJ in proj_pj_info() * Change length of filename member in PJ_INIT_INFO and PJ_GRID_INFO to 260 (MAX_PATH)
2017-08-04Fix the Solaris 11.3 compilation erroredechaux
When _XOPEN_SOURCE 500 is defined on Solaris 11 the following error message is displayed : "Compiler or options invalid for pre-UNIX 03 X/Open applications and pre-2001 POSIX applications" As pthread_mutexattr_settype is available without _XOPEN_SOURCE defined, the easier way to fix the error is to disable it.
2017-07-25Expose pj_factors and pj_deriv in public API. (#546)Kristian Evers
Expose pj_factors and pj_deriv in public API. proj_derivatives() and proj_factors() has been introduced to the public proj.h API. The new functions are simply wrappers for the original functions. The h argument of the two functions has been omitted in the new wrappers as it does not seem to be used very much (if at all?).

2017-07-18Expanded *_ERROR* macros.Kristian Evers
Expanded *_ERROR* macros with calls to proj_errno_set() and proper returns when necessary. Defined a bunch of new PJD_ERR_ constants in projects.h that corresponds to the error numbers in pj_strerrno.c. A few unknown error numbers were replaced by existing ones in pj_strerrno.c.

2017-05-24Remove confusing macros.Elliott Sales de Andrade
The upper-case macro `VAR` casts the lower-case variable `var` to an expected type, but that usage obfuscates the variables to the casual reader. This is especially prevalent in the allocation function in which `var` is the correct type already, so both `var` and `VAR` are valid *and* in use. In any case, for those functions that don't obtain `var` in the correct type from their parameters, it's much simpler to just case once at the beginning.
