KINFO_GETFILE(3)	 BSD Library Functions Manual	      KINFO_GETFILE(3)

NAME
     kinfo_getfile -- function for getting per-process file descriptor infor-
     mation

LIBRARY
     System Utilities Library (libutil,	-lutil)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/user.h>
     #include <libutil.h>

     struct kinfo_file *
     kinfo_getfile(pid_t pid, int *cntp);

DESCRIPTION
     This function is used for obtaining the file descriptor information of a
     particular	process.

     The pid field contains the	process	identifier.  This should be the	a
     process that you have privilege to	access.	 The cntp field	allows the
     caller to know how	many records are returned.

     This function is a	wrapper	around sysctl(3) with the KERN_PROC_FILEDESC
     mib.  While the kernel returns a packed structure,	this function expands
     the data into a fixed record format.

RETURN VALUES
     On	success	the kinfo_getfile() function returns a pointer to an array of
     struct kinfo_file structures as defined by	<sys/user.h>.  The array was
     obtained by an internal call to malloc(3) and must	be freed by the	caller
     with a call to free(3).  On failure the kinfo_getfile() function returns
     NULL.

SEE ALSO
     free(3), kinfo_getvmmap(3), malloc(3), sysctl(3)
