#include <xtend/fast-file.h> -lxtend
SYNOPSIS
int ffpclose(ffile_t *stream)
ARGUMENTS
stream ffile_t stream opened by ffpopen(3)
DESCRIPTION
ffpclose(3) closes a stream opened by ffpopen(3), and waits for the child process to complete and returns its exit status.The ffile_t system is simpler than and several times as fast as FILE on typical systems. It is intended for processing large files character-by-character, where low-level block I/O is not convenient, but FILE I/O causes a bottleneck.
RETURN VALUES
Exit status of the child process spawned by ffpopen(3), or -1 on errorEXAMPLES
ffile_t *instream;
if ( (instream = ffpopen("xzcat file.xz", O_RDONLY)) == NULL )
{
fprintf(stderr, "Failed to read xzcat file.xz.n");
exit(EX_NOINPUT);
}
ffpclose(instream);
