strspn

Defined in header <string.h> 
size_t strspn( const char *dest, const char *src );
+

Returns the length of the maximum initial segment (span) of the null-terminated byte string pointed to by dest, that consists of only the characters found in the null-terminated byte string pointed to by src.

+

The behavior is undefined if either dest or src is not a pointer to a null-terminated byte string.

+

Parameters

+ + +
dest - pointer to the null-terminated byte string to be analyzed
src - pointer to the null-terminated byte string that contains the characters to search for

Return value

The length of the maximum initial segment that contains only characters from the null-terminated byte string pointed to by src

+

Example

#include <string.h>
+#include <stdio.h>
+ 
+int main(void)
+{
+    const char *string = "abcde312$#@";
+    const char *low_alpha = "qwertyuiopasdfghjklzxcvbnm";
+ 
+    size_t spnsz = strspn(string, low_alpha);
+    printf("After skipping initial lowercase letters from '%s'\n"
+           "The remainder is '%s'\n", string, string+spnsz);
+}

Output:

+
After skipping initial lowercase letters from 'abcde312$#@'
+The remainder is '312$#@'
