STRPBRK(3)						   BSD Library Functions Manual 						STRPBRK(3)

NAME

     strpbrk -- locate multiple characters in string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     char *
     strpbrk(const char *s, const char *charset);

DESCRIPTION

     The strpbrk() function locates in the null-terminated string s the first occurrence of any character in the string charset and returns a
     pointer to this character.  If no characters from charset occur anywhere in s strpbrk() returns NULL.

SEE ALSO

     memchr(3), strchr(3), strcspn(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3), wcspbrk(3)

STANDARDS

     The strpbrk() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

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

STANDARDS

     The strspn() and strcspn() functions conform to ISO/IEC 9899:1990 (``ISO C90'').
