NAMEstrgsub - substitute all occurences of pattern with another string
SYNOPSIS
#include <publib.h>
int strgsub(char *str, const char *pat, const char *sub, size_t max);
DESCRIPTIONstrgsub finds all occurences of the pattern pat in the string str
(using a method similar to strstr(3) to find the occurrences, i.e., no
regular expressions), and replaces each with sub. If pat does not occur
in str, no substitution is made. The size (including the terminating
'\0') of the string after the substitutions may be at most max chars.
If it would be larger, no substitutions are made.
Of course, if sub is an empty string, the occurences of the pattern are
deleted from the string.
RETURN VALUEstrgsub returns the number of substitutions made, or -1 if the result
would not have fit into max chars.
EXAMPLE
To substitute every "foo" with "bar" in a line, one might do the fol‐
lowing.
strgsub(line, "foo", "bar", strlen(line)+1);
