Provides bindings for ported functions of the c standard library.

Functions

Function	Description
abs	Returns the absolute value of an integer
atoi	Converts a c string (int8*) to an integer
exit	Cleans resources and terminates the calling process immediately
fprintf	Writes a formatted c string (int8*) to a specified file stream
free	Deallocates the memory previously allocated by malloc, calloc, or realloc
fscanf	Reads formatted input from a file stream
getchar	Reads the next character from standard input
isdigit	Checks if a character is a digit ('0' to '9')
isspace	Checks if a character is a whitespace character
malloc	Retuns a pointer to size bytes of uninitialized storage
memcpy	Copies count bytes from the object pointed to by src to the object pointed to by dest
memset	Fills a block of memory with the specified value
printf	Writes a formatted c string to standard output
puts	Writes a c string to standard output, followed by newline
realloc	Reallocates previously allocated memory to a new size
scanf	Reads formatted input from standard input
strcat	Appends one c string to the end of another
strchr	Searches for the first occurrence of a character in a c string
strcmp	Compares two c strings lexicographically
strcpy	Copies one c string to another
strdup	Duplicates a c string by allocating memory for the new one
strlen	Returns the length of a c string
strncat	Appends a specified number of characters from one c string to another
strncmp	Compares a specified number of characters from two c strings
strncpy	Copies a specified number of characters from one c string to another
strrchr	Searches for the last occurrence of a character in a c string
strstr	Finds the first occurrence of a substring in a c string
strtoll	Converts a c string to int64 (long long int)

Warnings

Warning

The c standard library provided by ML is currently incomplete. To port a c standard library function ML, simply declare an external function with the same name as the c one along with its appropriate parameters and their ML-equivalent types. If such task interests you, please fork the project and add the required bindings along with the updated documentation and submit a pull request.
