strchr
Returns a substring that begins at the first matching occurrence of a specified character in a string.
string strchr(const char *string, char char)
The strchr
function returns a substring that matches the first occurrence
of a specified character, char, in the specified string,
string. If no match is found, strstr
returns 0. Note
that this function doesn't work with wide characters or multibyte characters.
The returned string is allocated out of scratch memory and is therefore valid only during
processing of the clause. If insufficient scratch memory is available,
strchr
doesn't run and an error is generated.
