CHARACTER CLASSIFICATION FUNCTIONS
This chapter documents general software library functions. The source code for all of
these functions is included with MPLAB-C17 in the c:\mcc\src\pmc directory, where
c:\mcc is the compiler install directory.
See the MPASM™ User's Guide with MPLINK™ and MPLIB™ (DS33014) for more
information about building libraries.
This chapter is organized as follows:
• Character Classification Functions
• Number and Text Conversion Functions
• Delay Functions
• Memory and String Manipulation Functions

char isalnum (static char ch);
ch
Character.
This function determines if ch is an alphanumeric character in
the ranges of:
A to Z(0x41 to 0x5A)
a to z(0x61 to 0x7A)
0 to 9(0x30 to 0x39)
This function returns 1 when the argument is within the
specified range of values; otherwise 0 is returned.
