NAME¶
strsub - substitute first occurrence of pattern with another string
SYNOPSIS¶
#include <publib.h>
char *strsub(char *str, const char *pat, const char *sub);
DESCRIPTION¶
strsub finds the first occurrence of the pattern pat in the string
str (using a method similar to strstr(3), i.e., no regular
expressions), and replaces it with sub. If pat does not occur in
str, no substitution is made.
Of course, if sub is an empty string, the pattern is
deleted from the string.
RETURN VALUE¶
strsub returns a pointer to the first character after the substitution,
or NULL if no substitution was made.
EXAMPLE¶
To substitute up to two occurrences of "foo" with "bar" in a
line, one might do the following.
p = strsub(line, "foo", "bar");
if (p != NULL)
strsub(line, "foo", "bar");
