SYNOPSIS

#include <string.h>

char *strrchr(

const char *s,

int c);

PARAMETERS

s Speciﬁes the string to search.

c Speciﬁes a character, expressed as an int data type, to search for.

DESCRIPTION

The strrchr() function locates the last occurrence of the integer speciﬁed by the c parameter,

which is converted to a char value, in the string pointed to by the s parameter. The terminating

null character is treated as a part of the string pointed to by the s parameter.

If c is a null byte (’\0’), the function locates the terminating null byte of s.

RETURN VALUES

Upon successful completion, this function returns a pointer to the matching character in the

scanned string. When the character speciﬁed by parameter c is not found, a null pointer is

returned.

ERRORS

None. This function does not set errno.
