gv_fopen()

FILE * gv_fopen	(	const char *	filename,
		const char *	mode
	)

open a file, setting close-on-exec

Generally, library code should set close-on-exec (O_CLOEXEC) on file descriptors it creates to avoid child processes of concurrent fork+exec operations accidentally inheriting copies of the descriptors. It is tricky to achieve this without races. This function attempts to avoid the common problems when trying to do this with fopen.

Parameters

filename	A filename, as you would pass to fopen
mode	A mode, as you would pass to fopen

Returns

A file handle with close-on-exit set on success or NULL on failure
