NAME¶
buffer_peekc - read one char from buffer
SYNTAX¶
#include <libowfat/buffer.h>
int buffer_peekc(buffer* b,char* x);
DESCRIPTION¶
buffer_peekc(b,x) is like buffer_get(b,x,1) but without advancing the buffer pointer. If you call it again, or call buffer_getc after it, you will get the same data again.
RETURN VALUE¶
buffer_peekc returns 1 on success, 0 when at the end of the file, or -1 if there was an I/O error (setting errno appropriately).
