LIBRARY ROUTINE

kstrstr - find a substring within a string

LIBRARY CALL

char *kstrstr(
   const char *istr,
   const char *sub_str)

INPUT

OUTPUT

none

RETURN VALUE

If the sub_str is found in istr, a pointer indicating the address of the first character of the substring within the istr string is returned. If the substring is not a part of the input string, a NULL is returned.

This routine also protects against NULL on both the input and substring variables. If either is NULL, the value of NULL is returned.

DESCRIPTION

This function locates the first occurrence of one string in another. It is a replacement for the system library routine strstr(). This routine scans the input string, 'istr', for the first occurrence of a substring specified by 'sub_str'.
