STRCHR(3) Library Functions Manual STRCHR(3) NAME strchr, strrchr, strchrnul -- locate character in string LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <string.h> char * strchr(const char *s, int c); char * strrchr(const char *s, int c); char * strchrnul(const char *s, int c); DESCRIPTION The strchr() function locates the first occurrence of c (converted to a char) in the string pointed to by s. The terminating null character is considered part of the string; therefore if c is `\0', the functions locate the terminating `\0'. The strrchr() function is identical to strchr() except it locates the last occurrence of c. The strchrnul() function is identical to strchr() except that if c is not found in s a pointer to the terminating `\0' is returned. RETURN VALUES The functions strchr() and strrchr() return a pointer to the located character, or NULL if the character does not appear in the string. strchrnul() returns a pointer to the terminating `\0' if the character does not appear in the string. SEE ALSO memchr(3), memmem(3), strcspn(3), strpbrk(3), strsep(3), strspn(3), strstr(3), strtok(3), wcschr(3) STANDARDS The functions strchr() and strrchr() conform to ISO/IEC 9899:1990 ("ISO C90"). The function strchrnul() is a GNU extension. HISTORY The strchrnul() function first appeared in glibc 2.1.1 and was added in FreeBSD 10.0. FreeBSD 14.3 February 13, 2013 STRCHR(3)
