NAME¶
strsub - substitute first occurence of pattern with another string
SYNOPSIS¶
#include <publib.h>
char * strsub(char *str, const char *pat, const char *sub);
DESCRIPTION¶
strsub finds the first occurence 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 occurences of "foo" with "bar" in a
line, one might do the following.
p = strsub(line, "foo", "bar");
if (p != NULL)
strsub(line, "foo", "bar");
