bgets(3G)                      DG/UX 5.4R3.00                      bgets(3G)


NAME
       bgets - read stream up to next delimiter

SYNOPSIS
       cc [flag ...] file ... -lgen [library ...]

       #include <libgen.h>

       char *bgets (char *buffer, sizet *count, FILE  *stream,
            const char *breakstring);

DESCRIPTION
       bgets 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.
