char *strchr(const char *s, int c); /* C only */
const char *strchr(const char *s, int c); // C++ only
char *strchr( char *s, int c); // C++ only
wchar_t *wcschr(const wchar_t *s, int c);
unsigned char * _mbschr(const unsigned char *s, unsigned int c);
Description
Scans a string for the first occurrence of a given character.
strchr scans a string in the forward direction, looking for a specific character. strchr finds the first occurrence of the character c in the string s. The null-terminator is considered to be part of the string.
For example:
strchr(strs,0)
returns a pointer to the terminating null character of the string strs.
Return Value
strchr returns a pointer to the first occurrence of the character c in s; if c does not occur in s, strchr returns null.
