manipulating char * strings

I am looking for, or looking to write if one doesnt exist, a library of functions to manipulate char * strings. I am aware that the string class already exists, but sending those type of strings across networks is a pain in the ***, i like to just stick with regular char * strings when dealing with sockets. The string class provides tons of extremely useful functions(replace, erase, find, etc.) and i would like a library that provides the same functionality for char * strings. I am also aware that class string provides functions to convert strings to char * strings, but the procedure is fairly annoying when it has to be done multiple times. So, im curious if anyone else has already written the library that i am describing?

edit: also i have several mini libraries i have written for various other things. when i use these i have to copy the desired header file into the working directory of my current project to use it. i want to create a folder of "My_Libraries"; how do i arrange it so that the compiler will search "My_Libraries" folder to find the desired header file?

<cstring>
Functions:
memchr Search buffer for a character
memcmp Compare two buffers
memcpy Copy bytes to buffer from buffer
memmove Copy bytes to buffer from buffer
memset Fill buffer with specified character
strcat Append string
strchr Find character in string
strcmp Compare two strings
strcoll Compare two strings using locale settings
strcpy Copy string
strcspn Search string for occurrence of charcter set
strerror Get pointer to error message string
strlen Return string length
strncat Append substring to string
strncmp Compare some characters of two strings
strncpy Copy characters from one string to another
strpbrk Scan string for specified characters
strrchr Find last occurrence of character in string
strspn Get length of substring composed of given characters
strstr Find substring
strtok Sequentially truncate string if delimiter is found
strxfrm Transform string using locale settings

thanks.
