The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
polygon – Draws a filled polygon. Allegro game programming library. Synopsis #include <allegro.h> void polygon(BITMAP *bmp, int vertices, const int *points, int color); Description Draws a filled polygon with an arbitrary number of corners.

poll_joystick – Polls the joystick. Allegro game programming library. Synopsis #include <allegro.h> int poll_joystick(); Description The joystick handler is not interrupt driven, so you need to call this function every now and again to update the global position values. Example: do { /* Get joystick input */ poll_joystick(); /* Process input for the first joystick…
PMIx_Put – Push a value into the client’s namespace Synopsis #include <pmix.h> pmix_status_t PMIx_Init(pmix_scope_t scope, const char key[], pmix_value_t *val); Arguments scope : Defines a scope for data "put" by PMI per the following: * PMI_LOCAL – the data is intended only for other application processes on the same node. Data marked in this way will…

Errors Notes See Also PMIx_Init(3) Authors PMIx.
PMIx_Init – Initialize the PMIx Client Synopsis #include <pmix.h> pmix_status_t PMIx_Init(pmix_proc_t *proc); Arguments proc : Pointer to a pmix_proc_t object in which the client’s namespace and rank are to be returned. Description Initialize the PMIx client, returning the process identifier assigned to this client’s application in the provided pmix_proc_t struct. Passing a parameter of NULL…
PMIx_Finalize – Finalize the PMIx Client Synopsis #include <pmix.h> pmix_status_t PMIx_Finalize(void); Arguments Description Finalize the PMIx client, closing the connection with the local PMIx server. Return Value Returns PMIX_SUCCESS on success. On error, a negative value corresponding to a PMIx errno is returned. Errors PMIx errno values are defined in pmix_common.h. Notes See Also PMIx_Init(3)…
PMIx_Commit – Push all previously PMIxPut_ values to the local PMIx server. Synopsis #include <pmix.h> pmix_status_t PMIx_Commit(void); Arguments none Description This is an asynchronous operation – the library will immediately return to the caller while the data is transmitted to the local server in the background Return Value Returns PMIX_SUCCESS on success. On error, a…
PMIx_Abort – Abort the specified processes Synopsis #include <pmix.h> pmix_status_t PMIx_Abort(int status, const char msg[], pmix_proc_t procs[], size_t nprocs); Arguments status : Status value to be returned. A value of zero is permitted by PMIx, but may not be returned by some resource managers. msg : A string message to be displayed procs : An…
