NAME

xt_ff_getc() - Read next character from a fast file stream

LIBRARY

#include <xtend/fast-file.h>
-lxtend

SYNOPSIS

int     xt_ff_getc(xt_ff_t *stream)

ARGUMENTS

stream  Pointer to an xt_ff_t object

DESCRIPTION

xt_ff_getc(3) reads a single character from a xt_ff_t stream opened by xt_ff_open(3).

The xt_ff_t system is simpler than and much faster than traditional 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

The character read, or EOF if no more data are available

EXAMPLES

xt_ff_t *stream;
int     ch;
if ( (stream = xt_ff_open(filename, O_RDONLY)) == NULL )
{


    fprintf(stderr, "Cannot open %s for reading: %s.n",


            filename, strerror(errno));


    exit(EX_NOINPUT);
}
while ( (ch = xt_ff_getc(stream)) != EOF )
{
}
xt_ff_close(stream);
