memmem() finds the start of the first occurrence of the byte array referenced by needle of length needlelen in the memory area haystack of length haystacklen.
memmem() returns a pointer to the beginning of the byte array, or NULL if the byte array is not found.
Earlier versions of the C library (prior to glibc 2.1) contained a memmem() with various problems, and application developers should treat this function with care.
