NAME

librock_countln - count consecutive characters up to and including next \0 \n

#License - #Source code - #Example Use -

SYNOPSIS

#include <librock/parse.h>

int librock_countln(
    const char *psz
);

DESCRIPTION

Returns count of consecutive characters up to and including next \0 \n IMPORTANT: this will go beyond \0 in a string. See example "Iterating Lines"

Typical use is to advance a pointer, replacing code like:

      while((*ptr != '\r')&&(*ptr != '\n')&&(*ptr != '\0')) ptr++;
      ptr++;

with:

      ptr += librock_countln(ptr);

Also used in parsing, where the count is needed to copy, compare, or write a limited number of characters starting at ptr. For example:

      fwrite(ptr,1,librock_countln(ptr),stdout);
