strchr(3) Library Functions Manual strchr(3) NAME
index, rindex, strchr, strrchr - Search for character in string 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 (' ') 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. RELATED INFORMATION
