strspn(3) [freebsd man page]

STRSPN(3)						   BSD Library Functions Manual 						 STRSPN(3)

NAME
strspn, strcspn -- span a string LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <string.h> size_t strspn(const char *s, const char *charset); size_t strcspn(const char *s, const char *charset); DESCRIPTION
The strspn() function spans the initial part of the null-terminated string s as long as the characters from s occur in the null-terminated string charset. In other words, it computes the string array index of the first character of s which is not in charset, else the index of the first null character. The strcspn() function spans the initial part of the null-terminated string s as long as the characters from s do not occur in the null-ter- minated string charset (it spans the complement of charset). In other words, it computes the string array index of the first character of s which is also in charset, else the index of the first null character. RETURN VALUES
The strspn() and strcspn() functions return the number of characters spanned. SEE ALSO
memchr(3), strchr(3), strpbrk(3), strrchr(3), strsep(3), strstr(3), strtok(3), wcsspn(3) STANDARDS
The strspn() and strcspn() functions conform to ISO/IEC 9899:1990 (``ISO C90''). BSD
