Syntax

  #include <string.h> 
   
  size_t strcspn (
     const char   *str,   
     const char   *charset);

Parameters

str

(IN) Points to a null-terminated string to scan.

charset

(IN) Points to a null-terminated set of characters to exclude from the length.

Return Values

Remarks

The strcspn function computes the length of the initial segment of the string pointed to by str, which consists entirely of characters not from the string pointed to by charset. The null-terminating character is not considered part of str.
