bgets(3G)bgets(3G)NAMEbgets - read stream up to next delimiter
SYNOPSIS
cc [flag ...] file ... -lgen [library ...]
#include <libgen.h>
char *bgets (char *buffer, size_t count, FILE *stream,
const char *breakstring);
DESCRIPTIONbgets reads characters from stream into buffer until either count is
exhausted or one of the characters in breakstring is encountered in the
stream. The read data is terminated with a null byte ('\0') and a
pointer to the trailing null is returned. If a breakstring character is
encountered, the last non-null is the delimiter character that terminated
the scan.
Note that, except for the fact that the returned value points to the end
of the read string rather than to the beginning, the call
bgets (buffer, sizeof buffer, stream, "\n");
is identical to
fgets (buffer, sizeof buffer, stream);
There is always enough room reserved in the buffer for the trailing null.
If breakstring is a null pointer, the value of breakstring from the
previous call is used. If breakstring is null at the first call, no
characters will be used to delimit the string.
EXAMPLES
#include <libgen.h>
char buffer[8];
/* read in first user name from /etc/passwd */
fp = fopen("/etc/passwd","r");
bgets(buffer, 8, fp, ":");
DIAGNOSTICS
NULL is returned on error or end-of-file. Reporting the condition is
delayed to the next call if any characters were read but not yet
returned.
