PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME
strrchr -- string scanning operation SYNOPSIS
#include <string.h> char *strrchr(const char *s, int c); DESCRIPTION
The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard. The strrchr() function shall locate the last occurrence of c (converted to a char) in the string pointed to by s. The terminating NUL character is considered to be part of the string. RETURN VALUE
Upon successful completion, strrchr() shall return a pointer to the byte or a null pointer if c does not occur in the string. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
Finding the Base Name of a File The following example uses strrchr() to get a pointer to the base name of a file. The strrchr() function searches backwards through the name of the file to find the last '/' character in name. This pointer (plus one) will point to the base name of the file. #include <string.h> ... const char *name; char *basename; ... basename = strrchr(name, '/') + 1; ... APPLICATION USAGE
None. RATIONALE

strspn -- get length of a substring SYNOPSIS
#include <string.h> size_t strspn(const char *s1, const char *s2); DESCRIPTION
The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard. The strspn() function shall compute the length (in bytes) of the maximum initial segment of the string pointed to by s1 which consists entirely of bytes from the string pointed to by s2. RETURN VALUE
The strspn() function shall return the computed length; no return value is reserved to indicate an error. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
