Function ffav_sys::av_strtok

pub unsafe extern "C" fn av_strtok(
    s: *mut c_char, 
    delim: *const c_char, 
    saveptr: *mut *mut c_char
) -> *mut c_char

Split the string into several tokens which can be accessed by successive calls to av_strtok().

A token is defined as a sequence of characters not belonging to the set specified in delim.

On the first call to av_strtok(), s should point to the string to parse, and the value of saveptr is ignored. In subsequent calls, s should be NULL, and saveptr should be unchanged since the previous call.

This function is similar to strtok_r() defined in POSIX.1.

@param s the string to parse, may be NULL @param delim 0-terminated list of token delimiters, must be non-NULL @param saveptr user-provided pointer which points to stored information necessary for av_strtok() to continue scanning the same string. saveptr is updated to point to the next character after the first delimiter found, or to NULL if the string was terminated @return the found token, or NULL when no token is found
