NAME

LIBRARY

Standard C Library (libc.so, libc.a)  

SYNOPSIS

#include <strings.h>

char *index(
        const char *s,
        int c);

char *rindex(
        const char *s,
        int c);

#include <string.h>

char *strchr(
        const char *s,
        int c);

char *strrchr(
        const char *s,
        int c);  

STANDARDS

Interfaces documented on this reference page conform to industry standards as follows:

index(), rindex():  XPG4-UNIX

strchr(), strrchr():  XPG4, XPG4-UNIX

Refer to the standards(5) reference page for more information about industry standards and associated tags.  

PARAMETERS

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

DESCRIPTION

The index() function locates the first occurrence of the integer specified by the c parameter, which is converted to an unsigned char, in the string pointed to by the s parameter. The terminating null byte is treated as part of the string pointed to by the s parameter.

The rindex() 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 byte is treated as a part of the string pointed to by the s parameter.

The strchr() and strrchr() functions provide the same functionality as the index() and rindex() functions, respectively.

If c is a null byte ('\0') in any of these functions, the function locates the terminating null byte of s.  

RETURN VALUES

Upon successful completion, these functions return a pointer to the byte in the scanned string. When the byte specified by parameter c is not found, a null pointer is returned.
